画了一张图,送给Writer,FileWriter,FileOutputStream,OutputStreamWriter,BufferedWriter,BufferedOutputStream傻傻分不清楚的同学!!

红色的是字符流路线,蓝色的是字节流路线,绿色的是字节转流字符流的路线(实现文件转码,读一行数据,等功能..) 希望帮的到大家 ,  有错的地方请多指教!

附字节流转字符流实现代码:

1. FileInputStream fis = new FileInputStream(fileA);
   
2. InputStreamReader isr = new InputStreamReader(fis,"utf-8");
   
3. BufferedReader br= new BufferedReader(isr);
   
4. 
   
5. FileOutputStream fos=new FileOutputStream(fileB);
   
6. OutputStreamWriter osr=new OutputStreamWriter(fos,"GBK");
   
7. BufferedWriter bw=new BufferedWriter(osr);
   
8. String buf;
   
9. while((buf=br.readLine())!=null){
   
10. bw.write(buf);
    
11. bw.newLine();
    
12. }

值得学习ing!
